How to get logged person's user_id from the database in php [duplicate]



This question already has an answer here:



I'm new to the Sessions topic so, I've been trying to get the logged person's id(column) from the userdetails table using sessions and insert it into the another variabl but couldn't achieve.I would appreciate if anyone could help me out on how to achieve.



PHP Code here.....



login.php


<?php

include("login_connect.php");
session_start();

if($_SERVER["REQUEST_METHOD"]=="POST")

// sent user name and password
$loginusername = mysqli_real_escape_string($conn,$_POST['userName']);
$loginuserpassword = mysqli_real_escape_string($conn,$_POST['userPassword']);

$sql = "SELECT id FROM userdetails WHERE UserName = '$loginusername' and UserPassword = '$loginuserpassword'";
$result = mysqli_query($conn, $sql);

// show result error_get_last
if (!$result)
printf("Error: %sn", mysqli_error($conn));
exit();


$row = mysqli_fetch_array($result,MYSQLI_ASSOC);
$active = $row['active'];

$count = mysqli_num_rows($result);

// If result matched $loginusername and $loginuserpassword, table row must be 1 row
if ($count == 1)
$_SESSION['name'] = $loginusername;
header("location: userwelcome.php");
else
echo "Your Login Name or Password is invalid";




?>

It's not clear what your actual issue is. The code you shown actually uses the session to store the username. So what's unclear about storing the user ID? As a friendly hint try to be consistent with your formatting choices. Sometime you had spaces around the = for assignments sometimes you had not. Also consider having a look at prepared statements at some point.

There's only the one piece of code for one file. If sessions isn't working, it's not in what you posted, but possibly in the other file(s). Use php's error reporting for this and var_dump() the session array.

var_dump()





You're not salt and hashing your passwords. Please fix that ASAP. You should consider making a User class and then saving that class in the session

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
